Abstract
This thesis investigates a DTP machine controlled by a dual inverter setup for potential CM voltage reduction. The machine parameters is validated by FEA simulation and experimental measurements. The machine is operated using FOC in Simulink and on a test bench setup. The machine model and operation is validated by comparing the simulation and measured results. Three PWM schemes are explored: SVM, interleaving SVM and ZCMV. The ZCMV shows a theoretical elimination of CM voltage. When implementing dead time in the simulation ZCMV shows pulses, that are dependent of dead time duration. Future work includes implementing the three strategies experimentally to verify if the CM voltage reduction is present on the physical machine using ZCMV.
